About 80 of all copper extracted comes from sulphide ores.A typical ore contains only 0.5 to 2.0 copper.It is a measure of the value of copper that it is worth extracting it from such small concentrations.The ore is a mixture of minerals and rock called gangue.The most common ...
The revised EPRI coal mining cost models represent a computerized process engineering approach to the analysis of production costs and mining requirements of either surface or underground mining projects. The models estimate all capital and operating costs

Aug 01, 2012 In situ leaching ISL is the dissolution and subsequent recovery of minerals from the subsurface by injection of a chemical solution. Because ISL of gold does not involve bulk rock mining, it has great potential to be substantially more environmentally friendly than conventional methods.
In situ leach ISL mining. ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock World Nuclear Association, 2012.
Heap leaching The process whereby leach liquor percolates through a pile of ore formed on an impervious base in such a way that the leachate can be collected for recovery of the metal values. In-situ leaching The process whereby leach liquor percolates through or is injected into the ore body in the place where it was originally deposited

In situ leach mining involves pumping a leaching solution called a lixiviant into an injection well near an extraction well, instead of extraction and milling procedures used in traditional mining. An in situ mine may have 50 or 100 injection wells. Uranium is removed from the leachate solution by ion exchange or some other mechanism.
